BRAKE SHOE;

Application filed February 23, 1928. Serial No. 256,128.

with the face plate.

A meritorious feature lies in the provision of a shoe of this character wherein a support- 1ng web having one edge engaging the face plate substantiallymidwaybetween: the two linear edges thereof hasportions formed integrally with the web offset laterally alternately on both sidesthereof into engagement withthe face plate in supporting relationship in proximity to its linear edges; and wherein the face plate is secured not only to the edge of the web but to the offset lateral projections thereof and wherein, if desired, the friction facing may be secured to the web with the same means which are employed to secure in part the web to the face plate.

Other meritorious advantages of my invention will appear from the following description, appended claims and accompanying drawing, wherein- Fig. 1 is aside elevation embodying my invention; 7

Figs. 2, 3 and 4 are'c ross-sectlonal views tively of Fig. 1, and,

Fig. 5 is a horizontal sectional View of a modified form of construction.

In the construction disclosed in the drawing I provide an arcuate sheet metal face plate 12 upon the outer periphery of which is secured a brake lining and upon the inner periphery of which is arranged in perpendicular relationship thereto a Web member 14. Reinforcing end portions 16 are arranged on opposite, sides of the web at the end in engagement with the face plate. The edge of the web may be welded at intervals throughout its length'tothe face plate.

In the construction illustratedfin Figs. 1 to 4 the web member is shown as consisting of a single thickness of metal and tongues 2-0 are punched laterally outwardl therefrom into supporting engagement th the face of a brake -shoe plate 12 leaving apertures 18 in the web. Thesetongues may be welded at 22 to the web. Tongues 26 are punched laterally outwardly from the end pieces 16 on opposite sides of the web into engagement with the face plate and'are shown as welded at 28 to the face plate and as leaving apertures 24 in the reinforcing portions. The laterally projecting integral portions are preferably punched from the web alternately on opposite sides as illustrated in Fig. '1.

In Fig. 5 I have illustrated a slightly modified form wherein the web is formed of a double thickness of material folded upon itself as illustrated in such figure and the tongues 20 are punched laterally outwardly upon one side fromone thickness and upon the other side from the other thickness, leaving a substantially unbroken web support for the face plate. I have here shown these tongues as secured by rivets 3O to-the face plate, which rivets also'hold the friction facing 10 thereon. Obviously the tongues 20 might be secured to the face plate in any suitable desired manner.

IVhat I claim is: V

l. A brake shoe comprising-a sheet metal face plate and having a sheet metal web extending linearly along one side thereof and arranged perpendicularly with respect thereto, said web having a substantially unbroken edge in engagement with the face plate and having integral portions punched from the web laterally into engagement with the face plate on both sides of the web. taken on lines 2+2, 33, and 4-4 respec- 2. A-b'rake shoe comprising a sheet metal faceplate and a sheet metal web extending linearly along one side thereof and arranged perpendicularly with respect thereto, said edge.

4:. A brake shoe comprising a sheet metal faceplate and a sheet metal web extending linearly along one side thereof and arranged perpendieuiarly Wltll respeet thereto, said.

web having one edge engaging the face plate and having integral portions offset laterally engaging the face plate spaced from said edge, said face plate being welded to said offset integral portions and to the edge of the web.

5. A brake shoe comprising a sheet metal face plate and a sheet metal web extending linearly along one side thereof and arranged perpendicularly with respect thereto, said web having laterally offset integral portions punched therefrom without interrupting the edge of theweb adjacent to the face plate, which portions supportingly engage said face plate. 7

j 6; A brake shoe comprising an arcuate face plate, an arcuate web arranged perpendicularly with respect thereto along one side thereof, said web having integral laterally offset portions supportingly engaging the face plate upon opposite sides of the web,

.sai-d portions being punched from the web without interrupting the edge adjacent to the face plate, said face plate being secured to the edge of the web at intervals and being secured to said offsetportions.

7 A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto, said web having one edge in engagement with the face plate and having portions punched through the web laterally and engagingthe face plate at a point spaced from the web.

8. A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto, and having its edge in engagement therewith, said web having integral portions projecting laterally therefrom alternately on opposite sides of the web into supporting engagement with the face plate.

9. A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto, said web being formed of ma terial of double thickness and having integral portions projecting laterally upon'one side from one thickness and supportingly engaging the face plate and having integral portions projecting laterally upon the opposite side from the other thickness and supportingly engaging the face plate.

10. A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto and having continuous line contact therewith throughout its length and interrupted contact therewith along a line spaced from and extending substantially parallel with said line of continuous contact.

11. A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto, having one edge in engagement therewith and having integral portions punched therefrom and doubled back outwardly thereover toward said edge into engagement with the face plate at points spaced from the edgeof the web.

12. A brake shoe comprising an arcuate sheet metal face plate and an arcuate sheet metal web extending linearly thereof along one side and arranged perpendicularly with respect thereto and having one edge engaged substantially throughout its length with the face plate and having integral portions punched therefrom on both sides engaged in supporting relationship with the face plate at spaced intervals throughout its length, said integral portions being so punched from the web as to be each connected therewith at the end adjacent to said edge and doubled outwardly therefrom toward said edge into engagement with the face plate.

13. A brake shoe comprising a sheet metal face plate and a sheet metal web extending linearly along one side thereof and arranged perpendicularly with respect thereto, said web having one edge engaging the face plate and having integral tongues punched laterally therefrom and forming arches engaging the face plate upon both sides of thejweb at points spaced from the edge of the web.
